Symptoms
Hypoglycaemia has not been seen with Medobis hydrochloride doses of up to 85g, although lactic acidosis has occurred in such circumstances. High overdose of Medobis or concomitant risks may lead to lactic acidosis.
Management
Lactic acidosis is a medical emergency and must be treated in hospital. The most effective method to remove lactate and Medobis is haemodialysis.

A reduction of diabetic complications has been shown in overweight type 2 diabetic adult patients treated with Medobis as first-line therapy after diet failure.
Pharmacotherapeutic group: Blood glucose lowering drugs, Biguanides
ATC Code: A10B A02
Mechanism of action
Medobis hydrochloride is a biguanide with antihyperglycaemic effects, lowering both basal and postprandial plasma glucose. It does not stimulate insulin secretion and therefore does not produce hypoglycaemia.
Pharmacodynamic effect
Medobis hydrochloride may act via 3 mechanisms:
(1) reduction of hepatic glucose production by inhibiting gluconeogenesis and glycogenolysis (2) in muscle, by increasing insulin sensitivity, improving peripheral glucose uptake and utilisation (3) delay of intestinal glucose absorption.
Medobis hydrochloride stimulates intracellular glycogen synthesis by acting on glycogen synthase.
Medobis hydrochloride increases the transport capacity of all types of membrane glucose transporters (GLUT) known to date.
In clinical studies, use of Medobis was associated with either a stable body weight or modest weight loss.
In humans, independently of its action on glycaemia, Medobis has favourable effects on lipid metabolism. This has been shown at therapeutic doses in controlled, medium-term or long-term clinical studies: Medobis hydrochloride reduces total cholesterol, LDL cholesterol and triglyceride levels.
Clinical efficacy and safety:
The prospective randomised (UKPDS) study has established the long-term benefit of intensive blood glucose control in adult patients with type 2 diabetes.
Analysis of the results for overweight patients treated with Medobis after failure of diet alone showed:
- a significant reduction of the absolute risk of any diabetes-related complication in the Medobis group (29.8 events/1000 patient-years) versus diet alone (43.3 events/1000 patient-years), p=0.0023, and versus the combined sulphonylurea and insulin monotherapy groups (40.1 events/1000 patient-years), p=0.0034;
- a significant reduction of the absolute risk of diabetes-related mortality: Medobis 7.5 events/1000 patient-years, diet alone 12.7 events/1000 patient-years, p=0.017;
- a significant reduction of the absolute risk of overall mortality: Medobis 13.5 events/1000 patient-years versus diet alone 20.6 events/1000 patient-years (p=0.011), and versus the combined sulphonylurea and insulin monotherapy groups 18.9 events/1000 patient-years (p=0.021);
- a significant reduction in the absolute risk of myocardial infarction: Medobis 11 events/1000 patient-years, diet alone 18 events/1000 patient-years (p=0.01).
Benefit regarding clinical outcome has not been shown for Medobis used as second-line therapy, in combination with a sulfonylurea.
In type 1 diabetes, the combination of Medobis hydrochloride and insulin has been used in selected patients, but the clinical benefit of this combination has not been formally established.
Paediatric population
Controlled clinical studies in a limited paediatric population aged 10-16 years treated during 1 year demonstrated a similar response in glycaemic control to that seen in adults.

Paediatric population
Controlled clinical studies in a limited paediatric population aged 10-16 years treated during 1 year demonstrated a similar response in glycaemic control to that seen in adults.
Absorption:
After an oral dose of Medobis hydrochloride, Tmax is reached approximately in 2.5 hours. Absolute bioavailability of a 500mg or 850mg Medobis hydrochloride tablet is approximately 50-60% in healthy subjects. After an oral dose, the non-absorbed fraction recovered in faeces was 20-30%.
After oral administration, Medobis hydrochloride absorption is saturable and incomplete. It is assumed that the pharmacokinetics of Medobis absorption is non-linear.
At the recommended Medobis doses and dosing schedules, steady state plasma concentrations are reached within 24 to 48 hours and are generally less than 1μg/ml. In controlled clinical trials, maximum Medobis hydrochloride plasma levels (Cmax) did not exceed 5μg/ml, even at maximum doses.
Food decreases the extent and slightly delays the absorption of Medobis. Following administration of a dose of 850mg, a 40% lower plasma peak concentration, a 25% decrease in AUC (area under the curve) and a 35 minute prolongation of time to peak plasma concentration were observed. The clinical relevance of these findings is unknown.
Distribution:
Plasma protein binding is negligible. Medobis hydrochloride partitions into erythrocytes. The blood peak is lower than the plasma peak and appears at approximately the same time. The red blood cells most likely represent a secondary compartment of distribution. The mean volume of distribution (Vd) ranged between 63-276L.
Biotransformation:
Medobis hydrochloride is excreted unchanged in the urine. No metabolites have been identified in humans.
Elimination:
Renal clearance of Medobis is >400ml/min, indicating that Medobis is eliminated by glomerular filtration and tubular secretion. Following an oral dose, the apparent terminal elimination half-life is approximately 6.5 hours.
When renal function is impaired, renal clearance is decreased in proportion to that of creatinine and thus the elimination half-life is prolonged, leading to increased levels of Medobis in plasma.
Characteristics in specific groups of patients
Renal impairment
The available data in subjects with moderate renal insufficiency are scarce and no reliable estimation of the systemic exposure to Medobis in this subgroup as compared to subjects with normal renal function could be made. Therefore, the dose adaptation should be made upon clinical efficacy/tolerability considerations.
Paediatric population:
Single dose study: After single doses of Medobis hydrochloride 500mg, paediatric patients have shown similar pharmacokinetic profiles to that observed in healthy adults.
Multiple dose study: Data are restricted to one study. After repeated doses of 500mg twice daily for 7 days, in paediatric patients, the peak plasma concentration (Cmax) and systemic exposure (AUC0-t) were reduced by approximately 33% and 40%, respectively, compared to diabetic adults who received repeated doses of 500mg twice daily for 14 days. As the dose is individually titrated based on glycaemic control, this is of limited clinical relevance.
Absorption:
After an oral dose of Medobis maximum plasma concentration (Cmax) is reached in approximately 2.5 hours (Tmax). Absolute bioavailability of a 500 mg or 850 mg Medobis tablet is approximately 50-60 % in healthy subjects. After an oral dose, the non-absorbed fraction recovered in faeces was 20-30 %.
After oral administration, Medobis absorption is saturable and incomplete. It is assumed that the pharmacokinetics of Medobis absorption is non-linear.
At the recommended Medobis doses and dosing schedules, steady state plasma concentrations are reached within 24 to 48 hours and are generally less than 1 microgram/ml. In controlled clinical trials, maximum Medobis plasma levels (Cmax) did not exceed 4 microgram/ml, even at maximum doses.
Food decreases the extent and slightly delays the absorption of Medobis. Following administration of a dose of 850 mg, a 40 % lower plasma peak concentration, a 25 % decrease in AUC (area under the curve) and a 35 minute prolongation of time to peak plasma concentration were observed. The clinical relevance of these findings is unknown.

When renal function is impaired, renal clearance is decreased in proportion to that of creatinine and thus the elimination half-life is prolonged, leading to increased levels of Medobis in plasma.
Pediatric population
Single dose study: After single doses of Medobis 500 mg, paediatric patients have shown similar phamacokinetic profile to that observed in healthy adults.
Multiple dose study: Data are restricted to one study. After repeated doses of 500 mg twice daily for 7 days in paediatric patients the peak plasma concentration (Cmax) and systemic exposure (AUC0-t) were reduced by approximately 33% and 40%, respectively compared to diabetic adults who received repeated doses of 500 mg twice daily for 14 days. As the dose is individually titrated based on glycaemic control, this is of limited clinical relevance.
Lactic acidosis
Lactic acidosis, a very rare, but serious metabolic complication, most often occurs at acute worsening of renal function or cardiorespiratory illness or sepsis. Medobis accumulation occurs at acute worsening of renal function and increases the risk of lactic acidosis.
Reported cases of lactic acidosis in patients on Medobis have occurred primarily in diabetic patients with impaired renal failure or acute worsening of renal function. Special caution should be paid to situations where renal function may become impaired, for example in case of dehydration (severe diarrhoea or vomiting, fever or reduced fluid intake), or when initiating antihypertensive therapy or diuretic therapy and when starting therapy with a non-steroidal anti-inflammatory drug (NSAID). In the acute conditions listed, Medobis should be temporarily discontinued.
Other associated risk factors should be considered to avoid lactic acidosis such as poorly controlled diabetes, ketosis, prolonged fasting, excessive alcohol intake, hepatic insufficiency and any condition associated with hypoxia (such as decompensated heart failure, acute myocardial infarction).
The risk of lactic acidosis must be considered in the event of non-specific signs such as muscle cramps, digestive disorders as abdominal pain and severe asthenia. Patients should be instructed to notify these signs immediately to their physicians if they occur, notably if patients had a good tolerance to Medobis before. Medobis should be discontinued, at least temporarily, until the situation is clarified. Reintroduction of Medobis should then be discussed taking into account the benefit/risk ratio in an individual basis as well as renal function.
Diagnosis:
Medicinal products that can acutely impair renal function (such as antihypertensives, diuretics and NSAIDs) should be initiated with caution in Medobis treated patients. Other risk factors for lactic acidosis are excessive alcohol intake, hepatic insufficiency, inadequately controlled diabetes, ketosis, prolonged fasting and any conditions associated with hypoxia, as well as concomitant use of medicinal products that may cause lactic acidosis.
Patients and/or care-givers should be informed on the risk of lactic acidosis.
Lactic acidosis is characterised by acidotic dyspnoea, abdominal pain and hypothermia followed by coma. Diagnostic laboratory findings are decreased blood pH (< 7.35), increased plasma lactate levels (>5 mmol/l) and an increased anion gap and lactate/pyruvate ratio. In case of lactic acidosis, the patient should be hospitalised immediately.
Physicians should alert the patients on the risk and on the symptoms of lactic acidosis.
Renal function
As Medobis is excreted by the kidney, creatinine clearance (this can be estimated from serum creatinine levels by using the Cockcroft-Gault formula) or eGFR should be determined before initiating treatment and regularly thereafter:
- at least annually in patients with normal renal function;
- at least two to four times a year in patients with serum creatinine levels at the lower limit of normal and in elderly subjects.
Decreased renal function in elderly subjects is frequent and asymptomatic. Special caution should be exercised in situations where renal function may become impaired, for example when initiating antihypertensive therapy, diuretic therapy or when starting therapy with a non-steroidal anti-inflammatory drug (NSAID).
In these cases, it is also recommended to check renal function before initiating treatment with Medobis.
Cardiac function
Patients with heart failure are more at risk of hypoxia and renal insufficiency. In patients with stable chronic heart failure, Medobis may be used with a regular monitoring of cardiac and renal function.
For patients with acute and unstable heart failure, Medobis is contraindicated.
Administration of iodinated contrast media
Intravascular administration of iodinated contrast agents may lead to contrast induced nephropathy, resulting in Medobis accumulation and an increased risk of lactic acidosis.5.
In patients with moderate renal impairment (eGFR between 45 and 60 ml/min/1.73m2), Medobis must be discontinued 48 hours before administration of iodinated contrast media and not be reinstituted until at least 48 hours afterwards and only after renal function has been re-evaluated and has not deteriorated further.
Surgery
Medobis must be discontinued at the time of surgery under general, spinal or epidural anaesthesia. Therapy may be restarted no earlier than 48 hours following surgery or resumption of oral nutrition and provided that renal function has been re-evaluated and found to be stable.
Paediatric population
The diagnosis of type 2 diabetes mellitus should be confirmed before treatment with Medobis is initiated.
No effect of Medobis on growth and puberty has been detected during controlled clinical studies of one year duration, but no long term data on these specific points are available. Therefore, a careful follow-up of the effect of Medobis hydrochloride on these parameters, in Medobis hydrochloride treated children, especially pre-pubescent children, is recommended.
Children aged between 10 and 12 years:
Only 15 subjects aged between 10 and 12 years were included in the controlled clinical studies conducted in children and adolescents. Although efficacy and safety of Medobis in these children did not differ from efficacy and safety in older children and adolescents, particular caution is recommended when prescribing to children aged between 10 and 12 years.
Other precautions
All patients should continue their diet with a regular distribution of carbohydrate intake during the day. Overweight patients should continue their energy-restricted diet.
The usual laboratory tests for diabetes monitoring should be performed regularly.
Medobis hydrochloride alone does not cause hypoglycaemia, but caution is advised when it is used in combination with insulin or other oral antidiabetics (e.g. sulphonylureas or meglitinides).

Lactic acidosis:
Lactic acidosis, a very rare but serious metabolic complication, most often occurs at acute worsening of renal function or cardiorespiratory illness or sepsis. Metformin accumulation occurs at acute worsening of renal function and increases the risk of lactic acidosis.
In case of dehydration (severe diarrhoea or vomiting, fever or reduced fluid intake), metformin should be temporarily discontinued and contact with a health care professional is recommended.
Medicinal products that can acutely impair renal function (such as antihypertensives, diuretics and NSAIDs) should be initiated with caution in metformin-treated patients. Other risk factors for lactic acidosis are excessive alcohol intake, hepatic insufficiency, inadequately controlled diabetes, ketosis, prolonged fasting and any conditions associated with hypoxia, as well as concomitant use of medicinal products that may cause lactic acidosis.
Patients and/or care-givers should be informed of the risk of lactic acidosis. Lactic acidosis is characterised by acidotic dyspnoea, abdominal pain, muscle cramps, asthenia and hypothermia followed by coma. In case of suspected symptoms, the patient should stop taking metformin and seek immediate medical attention. Diagnostic laboratory findings are decreased blood pH (< 7.35), increased plasma lactate levels (>5 mmol/L) and an increased anion gap and lactate/pyruvate ratio.
Administration of iodinated contrast agents
Intravascular administration of iodinated contrast agents may lead to contrast induced nephropathy, resulting in metformin accumulation and an increased risk of lactic acidosis.5.

However, patients should be alerted to the risk of hypoglycaemia when meformin hydrochloride is used in combination with other antidiabetic agents (sulfonylureas, insulin or meglitinides).
Posology
Adults (with normal renal function, GFR> 90 mL/min):
Monotherapy and combination with other oral antidiabetic agents:
- The usual starting dose is 500mg (5ml) or 850mg (8.5ml) Medobis hydrochloride 2 or 3 times daily given during or after meals.
- After 10 to 15 days the dose should be adjusted on the basis of blood glucose measurements. A slow increase of dose may improve gastrointestinal tolerability. In patients receiving a high Medobis hydrochloride dose (2 to 3 grams per day), it is possible to replace two Medobis hydrochloride 500mg doses (5ml) with one Medobis hydrochloride 1000mg (10ml) dose. The maximum recommended dose of Medobis is 3g (30ml) daily, taken as 3 divided doses.
- If transfer from another oral antidiabetic agent is intended, discontinue the other agent and initiate Medobis at the dose indicated above.
Combination with insulin:
Medobis and insulin may be used in combination therapy to achieve better blood glucose control. Medobis hydrochloride is given at the usual starting dose of 500mg (5ml) or 850mg (8.5ml) 2-3 times daily, while insulin dosage is adjusted on the basis of blood glucose measurements.
Patients with renal impairment
A GFR should be assessed before initiation of treatment with Medobis containing products and at least annually thereafter. In patients at increased risk of further progression of renal impairment and in the elderly, renal function should be assessed more frequently, e.g. every 3-6 months.
Medobis may be used in patients with moderate renal impairment, stage 3a (creatinine clearance [CrCl] 45-59 ml/min or estimated glomerular filtration rate [eGFR] 45-59 ml/min/1.73m2) only in the absence of other conditions that may increase the risk of lactic acidosis and with the following dose adjustments:
| GFR mL/min | Total maximum daily dose (to be divided into 2-3 daily doses) | Additional considerations |
| 60-89 | 3000 mg | Dose reduction may be considered in relation to declining renal function. |
| 45-59 | 2000 mg | Factors that may increase the risk of lactic acidosis (see 4.4) should be reviewed before considering initiation of Medobis. The starting dose is at most half of the maximum dose. |
| 30-44 | 1000 mg | |
| <30 | - | Medobis is contraindicated. |
Medobis is contraindicated in patients with severe renal failure (GFR <30 mL/min).
